UKT1C153MRD

The UKT1C153MRD is a radial-lead aluminum electrolytic capacitor designed for audio and general-purpose power applications. It delivers large bulk capacitance in a compact φ20 × 40 mm can, offering high ripple-current capability and wide operating temperature for demanding environments.

Built for reliability, the part supports extended endurance at elevated temperature and includes AEC-Q200 qualification. Typical use cases include smoothing and reservoir duties in audio power supplies where sustained ripple current and stable performance across temperature are required.

Key Features

• Capacitance & Tolerance — 15,000 µF (15 mF) with tolerance of -20% ~ 20% (measured at 20°C, 120 Hz).
• Rated Voltage — 16 V DC rating suitable for low-voltage audio and power-rail applications.
• Ripple Current Capability — Low-frequency ripple current of 2.43 A at 120 Hz and high-frequency ripple current of 2.795 A at 10 kHz, enabling effective smoothing under dynamic loads.
• Loss Angle (tan δ) — tan δ = 0.5 (measured at 20°C, 120 Hz), reflecting the capacitor's ESR characteristics at the nominal test condition.
• Temperature Range & Endurance — Operational from -55°C to +105°C with an endurance rating of 1000 hours at 105°C.
• Package & Mounting — Radial-lead can, size φ20 × 40 mm, lead spacing 10.0 mm with ±0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Leakage Current — Specified leakage current of 7,200 µA under the stated test conditions.
• Qualification — AEC-Q200 rating indicated in product specifications for enhanced reliability assurance.

Typical Applications

• Audio Power Amplifiers — Bulk reservoir and supply smoothing to support dynamic speaker loads and reduce audible supply ripple.
• Consumer Audio Equipment — Power-rail decoupling and energy storage in receivers, amplifiers, and powered speakers where compact high-capacitance solutions are required.
• Power Supply Filtering — DC-link and filtering duties in low-voltage supplies that require high ripple-current handling and wide temperature operation.

Unique Advantages

• High Capacitance in a Compact Can — 15,000 µF in a φ20 × 40 mm package conserves PCB area while delivering significant energy storage.
• Designed for Sustained Ripple — Specified ripple current at both low and high frequencies supports stable operation under real-world audio load profiles.
• Wide Temperature Operation — -55°C to +105°C range and 1000-hour endurance at 105°C provide resilience in temperature-variable environments.
• Through-Hole, Serviceable Form Factor — Radial-lead construction and 10 mm lead spacing simplify replacement and prototyping in hand-assembled or serviceable designs.
• Industry Qualification — AEC-Q200 listing supports designs that require documented reliability processes and testing.
